boxratiostats#

dataeval.metrics.stats.boxratiostats(boxstats: TStatOutput, imgstats: TStatOutput) → TStatOutput#

Calculates ratio statistics of box outputs over image outputs

Parameters:

boxstats (DimensionStatsOutput | PixelStatsOutput | VisualStatsOutput) – Box statistics outputs to perform calculations on
imgstats (DimensionStatsOutput | PixelStatsOutput | VisualStatsOutput) – Image statistics outputs to perform calculations on

Returns:

A dictionary-like object containing the computed ratio of the box statistics divided by the image statistics.

Return type:

DimensionStatsOutput | PixelStatsOutput | VisualStatsOutput

Note

DimensionStatsOutput values for channels, depth and distances are the original values provided by the box outputs

Examples

Calculating the box ratio statistics using the dimension stats of the boxes and images

>>> imagestats = dimensionstats(images)
>>> boxstats = dimensionstats(images, bboxes)
>>> ratiostats = boxratiostats(boxstats, imagestats)
>>> print(ratiostats.aspect_ratio)
